Abstract
The invention discloses an electronic book offline reading copyright protection system and a method thereof. The system comprises a storage module used for storing encrypted electronic book data, a decrypting module used for decrypting encrypted electronic book and an authority judging module; wherein the encrypted electronic book data contains a reading authority file corresponding to the electronic book, the authority judging module compares the identification of a client which has reading authority and is stored in the reading authority file with the identification of the client and judges whether the client has authority for reading the electronic book or not; if yes, the electronic book is decrypted by virtue of the decrypting module and the electronic book is opened, and if not the electronic book can not be opened. The invention can realize offline reading of document, and DRM protection on document is adopted, thus preventing spreading by copying. By registration of limited equipment, usable range of user can be limited, and DRM is bound to effective equipment hardware, so that only copying among equipment which are registered to be effective is allowable, otherwise reading can not be carried out.

Technical field
The invention belongs to field of computer technology, relate to a kind of electronic-book reading system, relate in particular to a kind of e-book off-line and read copyright protecting system; Simultaneously, the invention still further relates to a kind of e-book off-line and read copy-right protection method.
Background technology
Existing e-book reading software is common only at the unencrypted e-book, to the e-book of some payings, and usually can only online reading.Because a lot of users are by electronic equipment reading electronic books such as mobile phone, MP4, some electronic equipments do not possess the function of networking, and online reading has brought the inconvenience part to the user.
In addition,, can cause a plurality of users can read the paying e-book that a number of the account is downloaded, diminish copyright owner's interests if off-line is read the condition that throws the reins to.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of e-book off-line to read copyright protecting system, can realize the off-line reading, and can prevent to propagate by copy.
In addition, the present invention also provides a kind of e-book off-line to read copy-right protection method, can realize the off-line reading, and can prevent to propagate by copy.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of e-book off-line is read copyright protecting system, and described system comprises:
Memory module is in order to deposit the electronic book data of encryption; The electronic book data of described encryption includes the reading authority of this e-book correspondence; There is the sign that possesses the client of reading authority in this reading file;
Deciphering module is in order to the e-book deciphering to encrypting;
The authority determination module compares with the sign of described client in order to the sign that possesses the client of reading authority that will have in the described reading authority, judges whether this client has the authority of this e-book of reading; If possess the reading authority, then decipher this e-book and open, otherwise can't open this e-book by deciphering module.
As a preferred embodiment of the present invention, described system comprises the authority setting module, in order to when preserving e-book or afterwards, the hardware identifier of one or more clients is write the encrypted electronic book data of preservation.
As a preferred embodiment of the present invention, the hardware identifier that is designated client of described client.
As a preferred embodiment of the present invention, the ciphering process of e-book is: use user account, the download equipment sign generates the one-level key, uses irreversible MD5 algorithm to generate two groups of 128 keys, synthetic afterwards 256 keys use symmetrical SHA256 cryptographic algorithm to encrypt; The decrypting process of described deciphering module is the inverse operation of ciphering process.
A kind of e-book off-line is read copy-right protection method, and described method comprises:
The user obtains the electronic book data of encryption, and is kept in the client; The electronic book data of described encryption includes the reading authority of this e-book correspondence; There is the sign that possesses the client of reading authority in this reading file;
The user opens this e-book by client;
The sign that possesses the client of reading authority that has in the described reading authority is compared with the sign of described client, judge whether this client has the authority of this e-book of reading; If possess the reading authority, then decipher this e-book and open, otherwise can't open this e-book by deciphering module.
As a preferred embodiment of the present invention, described method comprises the authority setting step, when preserving e-book or afterwards, the hardware identifier of one or more clients is write the encrypted electronic book data of preservation.
As a preferred embodiment of the present invention, the hardware identifier that is designated client of described client.
As a preferred embodiment of the present invention, the ciphering process of e-book is: use user account, the download equipment sign generates the one-level key, uses irreversible MD5 algorithm to generate two groups of 128 keys, synthetic afterwards 256 keys use symmetrical SHA256 cryptographic algorithm to encrypt; Decrypting process is the inverse operation of ciphering process.
Beneficial effect of the present invention is: the e-book off-line that the present invention proposes is read copyright protecting system and method, can realize that the off-line of document is read, and in order to prevent to propagate by copy, document is adopted the DRM protection.By limited facility registration, can limit the scope that the user uses, DRM is tied to effective device hardware, only copies allowing between the effective equipment of registration, otherwise can't read.
